Anticoagulants
Medication class detail with safety cues and nursing action focus.
Anticoagulants
Examples: heparin, enoxaparin, warfarin, apixaban
Mechanism
Reduces clot formation by interfering with the coagulation cascade.
Used for
- Atrial fibrillation clot prevention
- DVT/PE treatment
- Mechanical valve anticoagulation for selected clients
Side effects
- Bleeding
- Bruising
- Heparin-induced thrombocytopenia
- Teratogenic risk with warfarin
Nursing actions
- Monitor bleeding, platelet trends, and ordered coagulation labs.
- Teach soft toothbrush/electric razor precautions.
- Know lab pairings: heparin often aPTT, warfarin PT/INR.
Hold / question cues
- Active bleeding
- Very high INR/aPTT per order
- Platelet drop with heparin
Antidote / reversal
- protamine for heparin
- vitamin K for warfarin
- agent-specific reversal for selected DOACs
NCLEX pearl
- Anticoagulants do not break clots; they help prevent growth and new clots.
